Help plz solve these equations by completing the square <br><br>x square + 12x =1
Hitman42 [59]

Answer:

x = - 6 ± \sqrt{37}

Step-by-step explanation:

Given

x² + 12x = 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(6)x + 36 = 1 + 36

(x + 6)² = 37 ( take the square root of both sides )

x + 6 = ± \sqrt{37} ( subtract 6 from both sides )

x = - 6 ± \sqrt{37} ← exact solutions

SCORPION-xisa [38]

Answer:

x = 50, y = 140

Step-by-step explanation:

The angles x, 40 and 90 lie on a straight line and sum to 180° , that is

x + 40 + 90 = 180

x + 130 = 180 ( subtract 130 from both sides )

x = 50

The angle vertically opposite x is congruent to x , that is 50°

y = 90 + 50 = 140
